Innovation has been a key differentiator for ARCHICAD since the beginning. ARCHICAD 21 introduces the highly-anticipated Stair Tool, featuring GRAPHISOFT's patent-pending Predictive Design� technology. ARCHICAD 21 delivers a number of other, important functional improvements in the fields of visualization, OPEN BIM, performance and productivity making this version one of the strongest in GRAPHISOFT's history.

Stair Tool
Designing stairs is one of the most complex tasks in architecture. ARCHICAD 21's new Stair Tool offers the most optimal stair designs to choose from in the context of the specific building.

Railing Tool
Complex yet configurable railing systems can be created that are associated with Stairs, Slabs, Walls, Roofs or Meshes.

Element Classification
An ARCHICAD design model can be described as a central BIM database that stores all project data and makes it accessible to any project stakeholder.

IFC Hotlinks
External IFC model content created by consultants - such as Structural or MEP engineers - can be placed as hotlinks into ARCHICAD 21 design projects as protected reference content.

Collision Detection
With the evolution of BIM as the de facto workflow, architects increasingly receive consultant information in a BIM format.

Touch Bar support for the Apple MacBook Pro
The Touch Bar is a Multi-Touch enabled strip of glass built into the keyboard for instant access to essential tools, right when you need them. By using the new MacBook Pro Touch Bar, architects can easily access the most relevant ARCHICAD controls and commands with ease.
